To @ZZ whom it may concern.-

Beit known that I, DON EDWARD McDoN- ALD, a citizen of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented new and useful Improvements in Oil-Cans, of which the following is a specification.

This invention relates to oil and gasolene cans which are designed more especially for 1o domestic or family use and which are provided with a handy-pump and telescopic discharge-pipe the upper section ot which can be lowered when not in use or raised to permit a lamp-bowl or other vessel to be placed under its spout.

The principal object of my invention is to provide the can with a simple pump of comparatively large capacity which permits the instant stoppage of the flow of oil from the zo pump when the lamp-bowl or other receptacle is filled, so as to prevent overflowing of the vessel, and which allows the pump-plunger and the upper movable section of the telescopic discharge-pipe to be pushed down into the can immediately after filling the vessel without discharging or spatterin g the oil over the top of the can, thus enabling the cover to be closed at once after filling a vessel. v

My invention has the further object to improve the construction of the canin other respects with a view of rendering the same more convenient in use.

In the accompanying drawings, Figure l is a vertical section of an oil-can provided with my improvements. Fig. 2 is a top plan View thereof, on a reduced scale, with the cover omitted. Fig. 3 is an enlarged sectional elevationof the upper portion of the hollow plunger-rod and the cover of the pump-bar- 4o rel at right angles to Fig. 1, showin g the means for interlocking said cover with said rod. Fig. 4 is a top plan view of said cover. Figs. 5 and 6 are horizontal sections in lines 5 5 and 6 6, Fig. 1.

Like letters of reference refer to like parts in the several figures.

A is the body of the can, and A/ its head or top plate, having the usual depressed central portion or pan A2, provided with the drain 5o opening or nipple a. i

B is the circular lid or cover applied to the depressed portion A2 of the head and preferably hinged thereto in a well-known manner.

O is the upright pump-barrel arranged in the can and having its open upper end 'se- 55 cured in an opening formed in the head A. The pump-barrel extends to the bottom of the can and is provided at its lower end with lateral inlet openings c and immediately above said openings with a diaphragm D, hav- 6o ing a passage d, which is controlled by an upa wardly-opening valve ol. This valve preferably consists of a i'lat disk resting loosely upon the diaphragm D and held against displacement by a suitable cage d2, secured to the diaphragm. The valve d while permitting the oil to rise through the passage of the diaphragm checks its return through the same.

E is the lower stationary section ot' the tele- 7o scopic discharge-pipe of the pump, which is connected with the pump-barrel above the diaphragm D and which extends upwardly through the head A of the can.

E is the upper movable section of the telescopic discharge-pipe, which slides in the lower section and is provided at its open lower end with a plunger or packing e for forming a tight joint.

e2 is the usaul spout of the movable pipe-sec- 8o tion which enters the drain-nipple ct when in its depressed position.

The discharge-pipe E E contains no checkvalve or other obstruction, so that the oil in said pipevis free to return into the pumpbarrel.

F is the plunger of the pump, which is suitably packed to form an air-tight joint around its periphery and which is provided with a port or passage f, through which the oil is al- 9o lowed to pass upwardly into the portion of the pump-barrel above the plunger when said passage is unobstructed.

f is an upwardly-opening relief-Valve applied to the plunger-passagef and consisting, preferably, of a iiat disk adapted to rest upon the upper yside of the plunger and confined against displacement by a raised yoke` or cage g.

h is the plunger-rod, which is preferably 10o hollow and connected with the plunger by the yoke'g. This rod extends upwardly through the open upper end of the pump-barrel and is provided at its upper end with a cross-bar 7l', forming a handle for operating the plunger.

t' is an operating-rod con nected with the relief-Valvef and extending upwardly through the hollow plunger-rod 7L and terminating in an eye or knob i', whereby said valve maybe held down on its seat by the same hand with which the operator grasps the handle of the plunger-rod.

j is a removable head or cover which closes the upper end of the pump-barrel. The upper end of the lattcris dared or funnel-shaped, as shown at k, to facilitate the pouring of the oil into the pump-barrel in iilling the can, and the barrel is provided immediately below its liaredportion with openings l, through which the oil poured into the barrel fiows into the body of the can. The cover j of the pumpbarrel is seated on a shoulder m, formed at the upper end of the pump-barrel, and is provided in its edge with a radial notch m', which receives the adjacent portion of the stationary discharge-pipe E. rlhe latter is provided at its upper end with an outwardly-projecting annular flange or bead m2, which overlaps the edge of said notch and prevents upward displacement of the cover. The cover may be further held down in place by a turn-button n, pivoted to the head of the can. The cover is preferably raised and removed by means of the plunger-rod 7L, which passes through a central opening of the cover. For this purpose the coverj is provided on its upper side concentrically with the plunger-rod with a collar o, having L-shaped slots o in diametrically opposite sides thereof. These slots are adapted to receive the end portions of the cross-bar 7L of the plunger-rod, which bar after being passed downwardly to the lower ends of the vertical branches of said slots is caused to enter their horizontal branches by giving the plungerrod a partial forward turn. lVhen the cover is thus interlocked with the plunger-rod and released from the turn-button n, the same can be raised by means of the valve-rod i and withdrawn laterally from under the flange m2 at the upper end of the stationary discharge-pipe E. ln removing the barrel-cover the plunger-rod is raised through the medium of the relief-valve f', which comes in contact with the under side of the yoke g and acts as a stop which limits the upward movement of the valve-rod t' in the plunger-rod. The plunger-rod is readily detached from the cover by turning the same backward sufficiently to release its cross-bar from the slots 0 in the collar o of the cover.

In filling a lamp-fount or other vessel the movable section E of the telescopic dischargepipe is raised and the fount placed under its spout in the usual manner. The operator then grasps the plunger-rod h by placing the fingers under its cross-bar h and the thumb of the same hand upon the eye t" of the valverod vl, so as to hold the relief-valve in its closed position, as shown in the drawings.

The plunger now acts like the solid plunger of an ordinary single-acting pump, and upon raising the same the oil is drawn through the inlet-openings c of the barrel and the suctionpassage d into the barrel. Upon depressing the plunger the suction-valve d is closed and the oil below the plunger is forced through the discharge-pipe E E' into the vessel to be filled. The pump-barrel preferably has a comparatively large capacitysay about a quart-so that a fou nt of ordinary size can be filled with a single stroke of the plunger. The delivery of the oil may be instantly stopped by simply releasing the rod t' of the relief-valvef', when the oil in the pump-barrel below the plunger will open said valve and rise through the passagefof the plunger, and the oil in the discharge-pipe E E' will descend and a portion thereof return into the lower portion of the pump-barrel and ascend through the plunger-passage, the oil ascending through the plunger until it reaches the same level as the oil in the body of the can. After filling the vessel the plunger and the vertically-movable section E of the discharge-pipe can be immediately pushed down to their lowermost position, in which position they permit the cover of the can to be closed, and this is accomplished without discharging or spattering the oil, which ordinarily remains in said pipe, over the top of the can. This objection is overcome by the use of my improved pump, because the oil in the discharge-pipe is free to immediately settle therein and rise through the plunger-passage fpast the relief-valvef', which latter opens automatically under the upward pressure of the oil. In oil-cans of this class as hitherto constructed the plunger and the dischargepipe could not be pushed down into the can immediately after filling a vessel without discharging the oil which remains in the delivery-pipe, because the check-valve in said pipe prevented the return of the oil into the pump-barrel and the oil was therefore expelled from the pipe upon telescoping the same. To avoid this objection in such cans, the oil remaining in the discharge-pipe must be allowed to settle and leak past the valve in said pipe; but servants frequently do not wait until this occurs, and as a consequence forget or neglect to close the cover of the can, allowing the odor or vapor of the oil to escape into the room and rendering the can unsafe. By constructing the pump so that the plunger and the discharge-pipe can at once be lowered after filling a vessel the cover can be closed immediately and the duty of closing the same is therefore not likely to be forgotten or neglected.

lVhen it is desired to fill the can, the plunger-rod 7L is interlocked with the cover j of the pump-barrel, as hereinbefore described, and said cover is then removed. Oil is then poured into the flared upper end of the barrel, from which latter it iiows through the upper openings l of the barrel into the can-body.

IIO

By thus utilizing the barrel itself as a filler the use of a separate funnel is dispensed with and the oil-can can be filled in less time than by the use of a funnel placed in an opening or nipple in the head of the can.

The cover 7' of the pump-barrel is confined upon the plunger-rod by the cross-bar 7d, and the cover cannot therefore become lost or mislaid.

I claim as my invention- 1. In an oil-can, the combination with the body of the can, of a force-pump arranged therein and having its barrel provided in its lower portion with an inlet which com municates with the liquid-space of the can, a checkvalve applied to said inlet for preventing the return of the oil from the barrel into the can, a valveless discharge-pipe Which is connected With the pump-barrel above said check-valve and which permits any oil in said pipe to return into the pump-barrel, a plunger arranged in the pump-barrel and provided with a reliefpassage through Which the oil may ascend above the plunger, and a relief-valve applied to said plunger-passage and provided Witha closing-handle Which extends to the Lipper end of the pump-barrel, substantially as set forth. l
